HAIR DRYING BAG Ethel C. Brown, Mission, Kans.

Application March 15, 1954, Serial No. 416,135

1 Claim. (Cl. 34-99) This invention has to do with the field ofcosmetology, particularly as it relates itself to hair-dressingoperations and has for its most important object the provision ofstructure for facilitating the drying of the hair through use ofvirtually any type of apparatus capable of producing artificial currentsof air.

It is the most important object of the present invention to provide ahair drying bag in the nature of a hollow body for receiving the head ofhair to be dried and having an air inlet opening at one end thereofadapting the bag for releasable attachment to hair drying apparatus, thematerial from which the bag is made consisting of a suitable fabric orother porous material permitting outward flow of the moisture-entrainedair therethrough and obviating the collection of condensate within thebag and which is removed from the hair by the currents of air.

Another important object of the present invention is to provide anovate-oblong hollow body having opposed, open ends of differingdiameters and made from an initially fiat blank of flexible materialprovided with V- shaped notches presenting a series of trapezoidal tabs,all for the purpose of permitting the formation of a plurality of dartsin the finished article of manufacture so as to attain the properconfiguration in the finished drying bag.

Other objects include important details of construction such as the wayin which the openings in the bag are defined by elastic bands so thatthe bag may be held tightly against the head and releasably attached tothe drying apparatus; and the manner of providing relatively large,initial diameters in the openings so that the elastic bands may beexpanded to various diameters.

In the drawing:

Figure l is a side elevational view of a hair drying bag made accordingto my present invention showing the same in operative use.

Fig. 2 is an enlarged, side elevational view of the bag; and

Fig. 3 is a plan view of the blank from which the hair drying bag ismade.

Referring first to Fig. 3 of the drawing, there is illustrated a blankbroadly designated by the numeral 10, that includes a rectangularportion 12 defined by a pair of end edges 14 and 16, a longitudinal edge18, and an imaginary line 20 extending longitudinally of the paneladjacent its longitudinal axis.

Panel 10 is provided with a plurality of V-shaped notches 22 having apexends 24 in spaced alignment along the line or longitudinal edge 20 ofportion 12, defining a plurality of trapezoidal tabs 26. Tabs 26 havetheir bases coincident with the longitudinal line 20. The panel 10 maybe made from any suitable flexible material, but it is preferred thatthe same be made from a suitable fabric or other porous substance forreasons hereinafter to be made clear.

Blank 10 is used to form hair drying bag 28 shown in Figs. 1 and 2 ofthe drawing, which takes the form of a hollow, ovate-oblong body 30having opposed, open ends 2,820,305 Patented Jan. 21, 1958 defined bycontinuous elastic bands 32 and 34 stitched or otherwise securedthereto.

In forming the body 30 from the blank 10, edges 14 and 16 of panelportion 12, are placed in close juxtaposition and in overlappingrelationship for joinder together by stitching or the like, which formsthe relatively large head-receiving opening and which is defined by theelastic 32 when the latter is applied to the body 30 along thelongitudinal edge 18. Thereupon, the relatively diverging edges of thetrapezoidal tabs 26 are placed in overlapping relationship in the samemanner and stitched together to present a plurality of longitudinallyextending, circumterentially spaced darts 36, projecting from therelatively small opening defined by elastic means 34 toward the elasticband 32. When the body 30 is then turned insideout, all seams and edgesare disposed therewithin.

It is seen that the said small opening that is defined by elastic 34, ismade up of the apex edges 38 of trapezoidal tabs 26, and the elasticband 34 is attached to the tabs 26 adjacent the said juxtaposed edges38.

The manner in which the bag 30 is placed in position to contain the headof hair to be dried, is illustrated in Fig. 1 of the drawing, and bythis showing, it is also seen how the elastic band 32 firmly engages thehead of the user throughout the circumferential length of the band 32.Figure 1 also illustrates the way in which the band 34 tightly gripsnozzle 40 of a suitable hair drying apparatus 42 capable of creatingartificial currents of air and directing the same into the bag 28against the hair to be dried.

Many devices as at 42 are equipped with means to heat the said currentsof air and under such conditions, the hair may be dried quickly andeasily through use of the drying bag forming the subject matter of thepresent invention.

It now becomes apparent why it is essential that the material from whichthe bag 28 is made, he imperforate except only for the openings thatreceive the head and the hair drying apparatus, yet be porous to theextent of permitting the air to escape from the bag 28 While the same isbeing used.

Still further, moisture that is removed from the hair by the air, willnot collect in the bag 30 but will be carried outwardly through thepores of the material from which bag 28 is made. Figs. 1 and 2 of thedrawing also indicate how the provision of elastic bands 32 and 34 forma plurality of folds 44 and 46 respectively, notwithstanding the factthat the edges 18 and 38 are initially straight. The maximum diameter ofthe head-receiving opening upon full expansion of the elastic band 32,is the same as the length of the longitudinal edge 18 of blank portion12, and the maximum diameter of the smaller opening when the elasticband 34 is expanded is the same as the combined lengths of the tab edges38.

Having thus described the invention, what is claimed as new and desiredto be secured by Letters Patent is:

As an article of manufacture, a hair drying bag comprising an initiallyfiat, elongated, flexible, porous panel having a rectangular portionincluding a pair of end edges and a pair of longitudinally extendingsides, there being a plurality of trapezoidally configured tabsextending outwardly from said portion along the entire longitudinallength of one side thereof, said tabs presenting a plurality ofidentical, equally spaced, V-shaped notches defined by respective,outwardly diverging side edges of the tabs, said notches terminating inequally spaced, apex ends disposed in substantial alignment along saidone side of the portion, the end edges of the rectangular portion beingslightly overlapped, and adjacent side edges of the tabs being disposedin respective slightly overlapping relationship; lines of stitchingjoining each of said overlapped edges respectively to present a hollow,ovate-oblong body having a 3 head-receiving opening formed by theopposite side of the portion and a second opening formed by theoutermost edges of the tabs, said second opening being appreciablysmaller than the head-receiving opening; a continuous, elastic bandsecured to said opposite side of the portion forming the head-receivingopening; and a second continuous, elastic band secured to the outermostedges of the tabs forming said second opening, said bands constrictingtheir respective openings to a designated size.
